Manual

Introduction

OEM400 series parking sensor systems are the new generation design with dual CPU & 4 individual channels to

detect obstacles behind the vehicle.

OEM400 series parking sensor is supplementary safety equipment specially designed for car reversing. There is

hidden peril when reversing because of the blind zone behind the car. After installing the parking sensor system,

when reversing, the display screen will show the distance from obstacles to the rear bumper.

Special Specifications

● No-ground detecting technology. The system will not detect obstacles lower than 1cm.● Unique ultrasonic resistance function can filter environmental ultrasonic waves effectively. ● System with sensitive adjustment guaranteed on false alarm.● Display with high brilliance under bright environment with the fine LED screen showing the obstacle direction.● Unique designed feature can be the display unit for dash mount, up mount or ceiling mount.● Unique designed feature can be either in Meters or Feet for distance indication.● All sensor cable plugs are sealed & detachable, easy for installation or warranty repair and replacement. ● Universal mount OEM style control box can be quickly installed into any vehicle.

Using method:

When reversing, the parking sensor will switch on automatically.

If there are no obstacles within two meters behind the car, it will display “--”. As the car nears the obstacle, it will

display the distance between the rear bumper of the vehicle and the obstacle, sending out four-converter buzz. The

display will show “P” when the distance is less than 0.3m or 1 foot. Please see Table 1.

The caution degree indicates degree of danger, and reminds the driver to be careful.

Taking inertia into consideration, it will show the distance with an extra 10cm (4inch).

Sensor installation:

Inspect the rear bumper, making sure there are no metal

braces or struts behind the locations where the holes

and sensor will be drilled. Spacing between the sensors

should be even, as shown in Fig 1.

The sensors are normally installed on the back bumper,

vertical to the ground or a bit upward tilting away from

the ground, if the installation position is lower than 50

cm to the ground. Please see Fig 2.

After drilling, please clean and smooth the edge of the

holes.

Notice: Please install the sensors with the arrowhead

upward if there is an arrow mark on the back end, or

they will mistakenly detect the ground as an obstacle.

For the OEM400T truck system, the sensor:

For sensors’ installation distance, please see Picture 6.

Paper adhesive tape is helpful to fix the sensors on the

back bumper.

For the OEM400T truck system, the sensor:

Use supplied screws to install all sensors under the back

of the cargo edge. See Fig 3.

Fig 3.

(&'��#�������� ������������ � �����

CAUTION:

1. Do not press the sensors during installation.

2. Install the sensors in the order of L, CL, CR and

R and the cable also.

3. Make sure all the sensor units are installed with

the “up” mark facing upwards.

4. Do not have anything sticking out of the sensors.

5. For other notices please see Figure 4.

Mounting the Control box:

Find a dry place inside the vehicle trunk at sidewall, clear any

dust before using Velcro pad and apply sticker.

Mounting the display screen:

Dash mounting display screen:

Use supplied double sided 3M tape to mount on the vehicle

dash. Do not mount the LED display screen in direct sunlight.

- Up mounting display screen:

Use the angle adapter to stick on the top of front windshield.

(Make sure to cut yellow wire at control box)

Or use the plastic adapter base to mount at rear side ceiling.

(&'��#��������� ������������ � �����

Connection & set up of the Control box

Please see Fig 5.

-Insert the sensors cable into the four sockets of control box L, CL and CR, R from left to right.

-Insert the power cable into PWR socket of control box.

Connect the Red wire of the power cable into the reversing light, and the Black wire to the ground.

-Insert plug of the display screen cable into DISP socket.

Select system display in Feet (Factory set in Meters):

-Cut Blue wire at left side of control box. The system will show Feet in the display.

Select display as up mount (Factory set in Dash mount):

-Cut Yellow wire at left side of the control box. The display unit works in up mount mold.

Testing process:

1. Park the vehicle outside on flat, even grounds in an open area.

2. Using a piece of cardboard as an obstacle, set at 2 m or 6 feet away from the rear bumper.

3. Start power of the vehicle and set gear into reverse; the parking sensor system should automatically turn on.

4. Slowly reverse the vehicle towards the obstacle. The display screen will show the distance & the Buzz tone will sound.

5. Place obstacle at left side behind vehicle. As the distance from the obstacle decreases, the left side of the LED

will first show green bars, then yellow and then red. By the time the obstacle is less than 0.3m or 1 Foot away

the entire left side of the LED will be on and the letter “P” will appear. At this time the vehicle must stop.

6. Repeat the same process for the right side.

7. Use the Buzz tone switch located at top of the display screen to adjust the Buzz tone volume.

Notice:

1. Do not press or pound the sensor.

2. Please clear any ice, snow, salt or other dust from the surface of the sensors in time.

3. As the system does not connect to car braking machinery, please brake immediately once the urgent buzz is heard.

(&'��#���������� ������������ � �����

CAUTION:

Possibilities of detection failure

According to the ultrasonic detecting principle, some obstacles may cause detection failure under the

conditions below:

1. A vertical obstacle much lower than the sensor, such as a pillar, a curve, the corner of a wall or a tilted pillar.

2. Objects such as metal net fences, narrow and rounded or triangular poles.

3. Ultrasonic wave projections that are difficult to detect, from objects such as bicycle wheels.

4. Objects with wave-absorbing material such as cotton or foam.

Number Problem Solution

1 No display when reversing

1. Make sure power and revering light are on.

2. Make sure power cable is connected to control box with correct

pole at DISP

3. Make sure display screen cables are correctly connected to control

box

2 Display but no buzz

1. Check the Buzz volume control switch

2. Make sure the screen cable is connected to DISP socket of control

box

3 Wrong digital display

1. Display may be disturbed by pressure from car washing, or another

parking sensor may be working nearby

2. Make sure sensor is not installed facing the ground

3. Ensure that the turning face of sensor is not inclined or upside down

4. Check if all plugs and joints are firmly connected
